Rayners installed 4 x Haier Heat Pump Chillers connected together and controlled by a ModBus connection to the sit wide BMS.

The chillers run in heating only configuration and provide 45/40 degree water to the under floor manifolds and low temperature hot water radiators around the hospital and apartment blocks.

2-pipe was chosen to allow for the project to be extended as demand increases. It is envisaged the final stages will be completed in late 2018.

Other Haier chillers have been installed at Distinction Hotel Palmerston North and IRD
